Subject: [PATCH] Add DeprecationWarning in test environments

Many deprecations are triggered early (on imports, for example)
before the warnings are enabled by the WarningsFixture in the
base test class.
To make sure all DeprecationWarning messages are emitted we
enable them via the PYTHONWARNINGS environment variable.
